|Storm is proud to showcase several of the most dynamic asymmetrical core designs on the market such as the Catalyst Core, the same core used throughout the Crux™ series. The coverstock GI-20 is named for Game Improvement – 2020 and was developed to help maximize performance in today’s complex bowling environment. Combined these provide an easy length to late mid-lane, GI-20 shines in frictionless environments. Its reaction is emphasized in the transition areas between ball motion phases – skid, hook, and roll. Simply put, it never misses the spot. And it can recover from just about anywhere. Colour: White/Copper/Graphite. Colours do vary somewhat from that shown.
